LOUIS J. BANDEMER, OF PLATO, MINNESOTA.

WIRE=STRETCHER.

SPIEOIFKCATION forming part of Letters Patent No. 691,521, dated January 21, 1902.

Application filed June 13, 1901. Serial No. 64,385. (No model.)

To (all whom it may concern: 7

Be it known that I, LoUIs J. BANDEMER, a citizen of the United States, residing at Plato, in the county of McLeod, State 'of Minnesota, have invented certain new and useful Improvements in WVire-Stretchers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wire-stretchers; and it has for its object to provide a construction which will be simple and cheap of manufacture and in which the wire may be placed under high tension, further objects and ad vantages of the invention being apparent from the following description. 7

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a plan View showing the complete stretcher. Fig. 2 is a central longitudinal section.

Referring now to the drawings, the present wire-stretcher consists of a frame including the sides 5 and 6 and the connecting end portions 7 and 8, and through one of these end portions 7 is formed a guide-opening 9, while in the opposite end portion are formed slots 10 and 11 and an intervening web 12. To permit of attachment of a chain to the frame of the stretcher, a double hook is provided, and it consists of a bar of metal bent into U shape and engaged around the web above mentioned, the sides of this U -shaped bar being brought toward each other, as shown, to prevent displacement from the web, and the extremities thereof being bent in opposite direction to form the hooks, as shown. One of these hooks is engaged with an end link of a chain 16 and is closed, so as to prevent disengagement, and the opposite end link of the chain is adapted for engagement with the second hook, it being understood that to fasten the stretcher-frame to a post the chain is first passed around the post, and its free end is then engaged with the open hook.

In the sides 5 and 6 of the frame are formed the pairs of alined perforations which form bearings for the shafts 21 and 22. On the shaft 21 and within the inclosure of the frame is fixed a spool 23, having a perforation 24 formed diametrically thereof, and on the outer end of the shaft is fixed a gear-wheel 25, which meshes with a second gear-wheel 26 on the shaft 22, which latter has a squared end, as shown, to receive a crank. The shaft 22 has also a spool 28 fixed thereon between the sides of the frame, and at the end of the spoolis a ratchet-wheel 29, in operative relation to which is disposed a pawl 30, which holds the drums against return movement. The drums may be shrunken upon their shafts to prevent rotation thereon. Engaged with the perforation of the first drum is the end of a wire cable 32, which is taken rearwardly and around the second drum and then forwardly and through the perforation in the end of the frame, the outer end of this cable being provided with a wire clip, as shown. With this construction it will be seen that the chain may be passed around a post and the clip engaged with a wire to be tightened, after which the crank on shaft 22 may be rotated, when both shafts will rotate, owing to the engagement of the gears at the outer ends thereof, and the drum on shaft 21 will be operated to wind up the cable and stretch the Wll'e.

What is claimed is-- A wire-stretcher comprising a frame including sides and end pieces, one of the end pieces having an opening therethrough and the other end piece having a reduced portion forming a web, an iron engaged around the web and having terminal'hooks, an attaching-chain engaged with one of the hooks and adapted for engagement with the other hook, shafts rotating in the sides of the frame and having drums fixed thereto within the inclosure of the frame, a cable attached to one of the drums and passed around the other drum and through the guide-opening of the frame, intermeshing gearing at the ends of the shafts, a ratchet-wheel upon one of the shafts and within the frame, and means for rotating the shaft.

In testimony whereof I hereunto sign my name, in the presence of two subscribing witnesses, on the 8th day of April, 1901.

LOUIS J. BANDEMER.
